Hi list I am unable to download a JPG image from an IP Webcam and feed a PictureBox, without creating a file-like object.
I'm using HttpClient to fetch the images asyncronously, but the buffer at last is only a string representation of its binary data. How do I convert this data into an actual image object for viewing in a PictureBox or DrawingArea? This is my code so far: ' Gambas class file PUBLIC $http AS HttpClient PRIVATE $pic AS String PUBLIC SUB Form_Open() $http = NEW HttpClient AS "MyStream" $http.Async = TRUE $http.Timeout = 3 $http.URL = "http://192.168.1.10:4500/axis-cgi/jpg"; & "/image.cgi?resolution=320x240" END PUBLIC SUB Timer1_Timer() $http.Get END PUBLIC SUB MyStream_Read() DIM buffer AS String READ #LAST, buffer, Lof(LAST) $pic &= buffer END PUBLIC SUB MyStream_Finished() ' Here I want to feed the picturebox with the buffered JPG ' but $pic only contains a string repr of the binary image PictureBox1.Refresh END PUBLIC SUB btnStart_Click() Timer1.Start END PUBLIC SUB btnStop_Click() Timer1.Stop END PUBLIC SUB btnExit_Click() Timer1.Stop ME.Close END I'd like to avoid using a file, is it possible to do from RAM?
